Discoveryopt® MS 3–9×50 IR SFP MOA Riflescope

The Discoveryopt MS 3–9×50 IR SFP MOA combines a 3–9× magnification range, 50 mm objective lens, and a red illuminated reticle in the second focal plane. Its MOA-based turrets provide a 0.25 MOA click value and can be locked to help prevent unintended adjustments. The riflescope also features fixed parallax at 100 yd, a 1 in / 25.4 mm main tube, nitrogen-purged construction, and an IP66 rating.

Second Focal Plane Reticle with Red Illumination

The MOA-L reticle is located in the second focal plane, meaning its apparent size remains constant as magnification changes. Red illumination with 6 brightness settings improves reticle visibility against dark or low-contrast backgrounds. The illumination system is powered by one CR2032 battery.

0.25 MOA Adjustments and Locking Turrets

Each elevation and windage click equals 0.25 MOA, corresponding to approximately 7.3 mm at 100 m. The riflescope provides 70 MOA of total elevation travel and 70 MOA of total windage travel. Both turrets can be locked after adjustment to reduce the risk of accidental rotation during handling or transport.

50 mm Objective Lens and 3–9× Magnification

The 50 mm objective lens is paired with an exit pupil ranging from 16.3 to 5.5 mm. The manufacturer specifies a field of view of 13.3–4.5 m at 100 yd, equivalent to approximately 14.5–4.9 m at 100 m. Eye relief ranges from approximately 83 to 72 mm depending on the selected magnification.

Fixed Parallax at 100 Yards

Parallax is factory-set at 100 yd, or approximately 91.4 m. The riflescope therefore has no user-adjustable parallax control.

One-Inch Main Tube and IP66 Protection

The riflescope features a 1 in / 25.4 mm main tube, measures 313 mm in overall length, and weighs 450 g. The objective bell has an external diameter of 57 mm. Nitrogen purging helps prevent internal fogging, while the IP66 rating provides dust-tight protection and resistance to powerful water jets. The manufacturer rates this model for 5.56 NATO recoil.

Included Accessories

The package includes the riflescope, lens cover, cleaning cloth, user manual, 2 specification cards, and a warranty and inspection card. Scope rings are not included and must be selected separately for the 1 in / 25.4 mm main tube.
